要約 (任意): (英) Bovine lactoferrin (bLF) modulates the production of proinflammatory cytokines including tumor necrosis factor (TNF)-alpha, and may thus control alveolar bone destruction associated with periodontitis. In this study, the effects of bLF on mRNA expression in lipopolysaccharide (LPS)-stimulated osteoblasts (OBs) and on LPS-induced osteoclastogenesis were examined. The inhibitory effects of oral administration of liposomal-bLF (L-bLF), which improved the robustness of bLF to digestive enzymes, on alveolar bone resorption using LPS-induced periodontitis rat model are also reported. Three groups of 7-week-old male Wistar rats were treated with L-bLF (L-bLF group), bLF (bLF group), or the vehicle (control group) in drinking water (n=6 in each group). On day 7, LPS was topically applied into the gingival sulcus. Number of osteoclasts and immunoexpression of TNF-alpha were analyzed. The bLF inhibited the upregulation of TNF-alpha-mRNA- and upregulation of receptor activator of NFkappaB (RANKL)-mRNA expression and eliminated downregulation of osteoprotegerin (OPG)-mRNA expression in LPS-stimulated OBs and reduced LPS-induced osteoclastogenesis in co-culture with primary OBs and bone marrow cells. In the control group, the number of osteoclasts increased after LPS treatment. The number of osteoclasts that appeared along the alveolar bone margin was significantly reduced (P<0.01) in the L-bLF but not in the bLF group. Furthermore, L-bLF suppressed upregulation of TNF-alpha immunoexpression in periodontal tissue and TNF-alpha and interleukin (IL)-1beta-mRNA level in gingival tissue. The results of this study indicate that oral administration of L-bLF significantly reduces alveolar bone resorption induced by LPS stimulation through inhibition of TNF-alpha production and modulation of RANKL/OPG balance in OBs. It is suggested that L-bLF could be a potent therapeutic and preventive agent for attenuating alveolar bone destruction in periodontitis patients.Laboratory Investigation advance online publication, 26 April 2010; doi:10.1038/labinvest.2010.80.  (日)    [継承]
